Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The read-only fileHandle property of the IDBFileHandle interface returns the IDBMutableFile object that produced this object.

Note: The three interfaces IDBMutableFile, IDBFileHandle, and IDBFileRequest are deprecated and only implemented for backward compatibility in Firefox. Do not use them anymore: consider using the File and Directory Entries API instead.
